IMPROVEMENT I'N ENvELoPEs.

Specification forming part of Letters Patent No. 184,617.. dated ovember 21, 1876; application filed October 20, 1875.

To all whom it may comem:l Be it known that I, WILLIAM H. HART, o

Chelsea. in the county of Sui'olk and State of' ceptacle as to receive the Whole or major part of the postage-stamp upon such projecting part ot' the border.

It is the object of this invention to render it practicable for the postoftice officials to cancel the stamps by punching 'out a portion thereof Without injury to the contents of the envelope, and thereby render it impossible for the evil-minded to removethe marks ot' cancellation from the stam p, which is now so common a practice, by means of washing in chemical prepara-tions.

In the drawing, Figure l is a plan view of an envelope provided with an indicated position for the stamp. Fig. 2 is also a plan view ot' an envelope, showing the stamp afxed. Fig. 3 is a similar view-,ibut shows the stamp canceled bypunching. FigAisa vertical section taken on line A B, Fig. 3. Fig. 5 is a similar section, but showing a double border or margin. j

In the drawings, a represents the pocket or receptacle in which theletter or other mailmatter is placed. vb is the border upon whichv the stamp c is aixed. d indicates the termito the envelope is shown, but it is doubled and secured by pasting upon both sides of the envelope.

By thus pasting the border or stamp-receptacle upon the envelope, instead of forming such border from an integral part of' the envelope, it can be produced at less cost than by the other method, and the break in the surface caused by such overlapping serves as an efficient guide to prevent the lnisplacement ot' the stamp when afxing it to the envelope.

I do not cla m an envelope provided with a border which'is formed by closing together a portion of the Walls thereof; but 1 What I do claim as my invention is- An envelope provided with a border or margin attached to the body of the envelope, and extending beyond it a sufficient distance to receive thestamp, substantially as described and shown.
